1, domestic low-temperature 4047 aluminum-silicon welding wire (melting point 580-620 degrees), combined with low-temperature aluminum powder welding, this method is more suitable for traditional aluminum water tank welding. Generally, the master who hangs the aluminum water tank welding brand uses this welding method more, and the cost is relatively low, but the welding root still has certain limitations and considerable difficulty.
2. For the low-temperature welding of 2.Viodin 303 low-temperature aluminum wire (melting point 430 degrees), oxyacetylene can be used as the heat source, or gas with a single gas source can be used. This welding method is more suitable for novice welding operation and does not need welding powder. Although the cost will be higher, the average cost is negligible for the value of repair.
3. Low-temperature aluminum welding wire M5 179 degrees/mixed flux M5 1-f, this welding method is characterized by low temperature, absolutely low, less than 200 degrees, so no one will burn the aluminum pipe when welding. Generally, it is mostly used for pinholes and small air holes, and even some parts that are not easy to disassemble can be welded as long as they are drained.
4. Low-temperature aluminum welding wire WEWELDING53 welding wire with a low temperature of 385 degrees is welded with a special root brush of 53. This kind of welding wire is characterized by subverting all welding methods of aluminum, welding with a root brush, and is not picky about the base material. Therefore, if the cracks in the general intercooler or large water tank are all inside, this kind of welding wire is advantageous.
